+Description:
+
+Texture border clamp cases test functionality added in
+EXT_texture_border_clamp extension. Tests set up a texture with a certain
+format, set border color to certain value, set one or more wrapping modes to
+CLAMP_TO_BORDER, and then proceed to render the texture to screen. The
+rendering result is then verified. Test cases also generate a reference image
+which may be useful when evaluating results.
+
+In formats.* subgroup, all GLES31 texture formats are tested. Each format is
+tested with power-of-two and non-power-of-two texture sizes using NEAREST and
+LINEAR filtering, and texture-gather fetching.
+
+In range_clamp.* subgroup, border color components are set to values that are
+not in the representable range of the internal format. The effective value is
+expected to be clamped to the valid range.
+
+In sampler.* subgroup, texture border color and wrapping mode are set using
+a sampler state.
+
+In per_axis_wrap_mode.*, texture wrap mode is not same in all S, T, and R
+directions. Wrapping is tested for 2D and 3D textures with multiple formats
+and with different sampling modes.
+
+In depth_compare_mode.*, depth texture border values are tested with compare
+mode set to COMPARE_REF_TO_TEXTURE.
+
+In unused_channels.*, border color has non-zero values in components that are
+not representable in the target formats. These components are expected to have
+no effect.
